Another grill cover bites the dust

I was in my 1986 Jetta diesel fully loaded as usual today. Cruising at about 55 mph. the outside temp was 100 F with a slight tailwind. I notice that the temp gauge is getting hotter than usual. Nearing the 3/4 mark.

My grill cover was held on with two drywall screws and some cable ties. I pulled over and removed all of it. Within a mile the gauge was back down to 1/4-1/3rd the way up the gauge.

If the trade of more aero vs a significantly hotter engine is the trade then I am going to use a small amount of fuel more.

Usually August is hotter than July around here. It may go back on in the mid fall but not sooner.
